Aim: We need to separate a solution to form a precipitate
Precipitate - the name for a solid that forms in a liquid during a chemical reaction
Hypothesis: I believe that the solution would separate.
Method:
1. Pour approximately 50 mL of copper sulfate solution into a beaker.
2. Add the same volume of sodium carbonate solution. A reaction will happen, you should see a cloudy blue precipitate form called copper carbonate.
3. Watch demo then fold filter paper to fit inside the funnel.
4. Place the funnel with the filter paper inside of it into the mouth of a conical flask.
5. Stir the mixture in the beaker then carefully pour it into the funnel.
6. Observe what happened.
Observation and Discussion: The mixture became cloudy and dark than what it was originally. It did not change color. When we began filtering the solution, the filtrate appeared clear. The residue was a gooey outcome of the copper sulfate, slime almost.
Conclusion: Copper sulfate cannot be filtered when mixed into a solution.
